Abstract: A new diagnostic assay of sperm function has been found for infertility treatment and monitoring programs. The hemizona assay (HZA) measures tight binding of human spermatozoa to the human hemizona pellucida.

Abstract: A method of inducing ovulation by administering exogenous human menopausal gonadotropins employs FSH as the exogenous human menopausal gonadotripin in the absence of exogenous LH, preferably in conjunction with a gonadotropin releasing factor antagonists. One particular application of the method is in vitro fertilization.

Abstract: A method for the treatment of infertility is described involving recruitment of more than one oocyte by a unique and hitherto undescribed combination of goandotropins, the harvest of these oocytes prior to their spontaneous ovulation and their fertilization by exposure to sperm in vitro so that the resulting concepti can be transferred to the uteri of the donors and so overcome several forms of infertility.

Abstract: A method of in vitro fertilization therapy, which includes means for inducing ovulation by administering an exogenous human menopausal gonadotropin preparation and human chorionic gonadotropin, harvesting the mature follicles, combining the ovum with spermatazoa in vitro and transferring the conceptus into the uterus is improved by employing FSH as the exogenous human menopausal gonadotropin in the absence of exogenous LH.

Abstract: Antibody to anti human chorionic gonadotropin and/or antibody to anti human chorionic gonadotropin-beta subunit labeled with technetium-99m, iodine-123, iodine-125 or iodine-131 are/is administered to a human after the human has been administered anti-hCG and/or anti-hCG beta. The biodistribution of the labeled composition accumulates at cancer sites, e.g. tumors that produce human chorionic gonadotropin (hCG), human chorionic gonadotripin-like material, and a compound similar to and/or identical to the beta-chain of chorionic gonadotropin, or mixtures thereof which would bind specifically to anti-hCG and/or anti-hCG-beta.

Abstract: Human Relaxin is recovered from human fetal membranes, and preferably from the chorion-decidua membranes.

Abstract: Partially desialylated human Chorionic Gonadotropin is used after menotropin administration to induce ovulation.

Abstract: This invention relates to certain 2-thiol-4,5-diphenyloxazole S-derivatives, to processes for their preparation and to therapeutic compositions containing them.
